2024-07-13include: ssp: round out fortification of current set of headersKyle Evans
ssp/ssp.h needed some improvements: - `len` isn't always a size_t, it may need casted - In some cases we may want to use a len that isn't specified as a parameter (e.g., L_ctermid), so __ssp_redirect() should be more flexible. - In other cases we may want additional checking, so pull all of the declaration bits out of __ssp_redirect_raw() so that some functions can implement the body themselves. strlcat/strlcpy should be the last of the fortified functions that get their own __*_chk symbols, and these cases are only done to be consistent with the rest of the str*() set.

2024-05-14ssp: appease -Wgnu-statement-expression-from-macro-expansionKyle Evans
It's a stupid warning, but some ports enable it by default and were already defining _FORTIFY_SOURCE, thus exposing the new macros immediately. This at least fixes the libfido2 build, perhaps others as well. While we're here, fix a fresh build of stand w/ FORTIFY_SOURCE enabled by not pulling in the ssp headers if _STANDALONE is defined. We do not have runtime support in libsa as of the time of writing. Reported by: netchild Sponsored by: Stormshield Sponsored by: Klara, Inc.
2024-05-13Add a build knob for _FORTIFY_SOURCEKyle Evans
In the future, we will Default to _FORTIFY_SOURCE=2 if SSP is enabled, otherwise default to _FORTIFY_SOURCE=0. For now we default it to 0 unconditionally to ease bisect across older versions without the new symbols, and we'll put out a call for testing. include/*.h include their ssp/*.h equivalents as needed based on the knob. Programs and users are allowed to override FORTIFY_SOURCE in their Makefiles or src.conf/make.conf to force it off.

2017-11-25include: General further adoption of SPDX licensing ID tags.Pedro F. Giffuni
Mainly focus on files that use BSD 2-Clause license, however the tool I was using mis-identified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. Notes: svn path=/head/; revision=326192

2002-08-21o Merge <machine/ansi.h> and <machine/types.h> into a new headerMike Barcroft
called <machine/_types.h>. o <machine/ansi.h> will continue to live so it can define MD clock macros, which are only MD because of gratuitous differences between architectures. o Change all headers to make use of this. This mainly involves changing: #ifdef _BSD_FOO_T_ typedef _BSD_FOO_T_ foo_t; #undef _BSD_FOO_T_ #endif to: #ifndef _FOO_T_DECLARED typedef __foo_t foo_t; #define _FOO_T_DECLARED #endif Concept by: bde Reviewed by: jake, obrien Notes: svn path=/head/; revision=102227
